Hi Fatguyslim,

I'm not sure if the few last posts have piqued your interest again or not, so this question may not be relevant.

But if you were to design and make your own bike bits for these higher stress areas and sell them to the public where do you stand in terms of liability in case of failure? Would you need to carry out your own stress and durability analysis on those safety critical items, and is that something you were planning anyway?

EDIT: Crossed with your post. Ignore - BS/EN testing mentioned in your post . . . apologies.
